CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No.10/944,925 filed on Sep. 20, 2004 (now U.S. Pat. No. 7,970,849), whichclaims the benefit of U.S. Provisional Application No. 60/504,379entitled filed on Sep. 19, 2003, both of which are hereby incorporatedinto the present application by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates generally to handheld electronic devices and, moreparticularly, to a handheld electronic device and a method for providinginformation representative of the times of certain communications in amessaging environment.

2. Background of the Invention

Numerous types of handheld electronic devices are known. Examples ofsuch handheld electronic devices include, for instance, personal dataassistants (PDAs), handheld computers, two-way pagers, cellulartelephones, and the like. Such handheld electronic devices are generallyintended to be portable, and thus are relatively small. Many handheldelectronic devices also feature wireless communication capability,although many such handheld electronic devices are stand-alone devicesthat are functional without communication with other devices. Withadvances in technology, handheld electronic devices are being configuredto include greater numbers of features while having relatively smallerform factors.

Electronic devices, including handheld electronic devices, are capableof numerous types of communication. One type of communication is“messaging”, and one type of messaging is “instant messaging” whichenables a first device to send a message on a more or less instantaneousbasis to a second device. With most all instant messaging, a givenelectronic device is provided with an interface that outputs the variouscommunications that have occurred between the electronic device andanother electronic device during a messaging “conversation”. A sampleoutput on an electronic device that is representative of the variouscommunications that have occurred during a conversation may be asfollows:

Hi Honey, how was your day?

<Brutal! Larry embarrassed me in front of everybody.

What a Jerk!

<Yeah, but I got him back later with a karate chop!

good for you.

In this example, incoming messages are indicated by a greater than “>”mathematical symbol, and outgoing messages are indicated by a less than“<” mathematical symbol. If the conversation continues quickly, i.e.,substantially without interruption, the messages do not need a timestamp on them. In the environment of a handheld electronic device, itwould be desirable to avoid unnecessary time stamps and otherunnecessary output since it occupies too much valuable space on thelimited display of the handheld electronic device.

In some messaging circumstances, however, it may be desirable forinformation regarding certain timing aspects of conversation to beavailable to a user. Nevertheless, the limited space available on adisplay of a handheld electronic device has made a solution difficult.It thus would be desirable to provide an improved handheld electronicdevice and an associated method that provide time data in a messagingenvironment.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

An improved handheld electronic device 4 in accordance with theinvention is indicated generally in FIG. 1 and is depicted schematicallyin FIG. 2. The exemplary handheld electronic device 4 includes a housing8 upon which are disposed an input apparatus 12, an output apparatus 16and a processor apparatus 20. The input apparatus 12 includes a keypad24 that can be said to include a plurality of keys 28.

The output apparatus 16 includes a display 50. The output apparatus 16can additionally include, for instance, additional indicators such aslights, and the like, and can additionally include an audible outputsuch as a speaker as well as other output devices.

The processor apparatus 20 includes a processor 52 that can be, forinstance, and without limitation, a microprocessor (μP), and it isresponsive to inputs from the input apparatus 12 and provides outputsignals to the output apparatus 16. The processor apparatus 20 furtherincludes a memory 56 that includes a routine 60 stored therein. Theexemplary routine 60 is a messaging routine that can provide a messagingcapability on the device 4. It is understood that the memory 56 likelyincludes a number of other routines that are not expressly mentionedherein. As employed herein, the expression “a number of” and variationsthereof shall refer broadly to any nonzero quantity including a quantityof one. The processor 52 interfaces with the memory 56, and the routine60 is executable on the processor 52.

The device 4 further includes a wireless communication system. As can beseen in FIG. 3, the device 4 with the routine 60 can interface with amessaging service 62 to wirelessly provide the messaging capability onthe device 4. In the depicted exemplary embodiment, the messagingservice 62 provides an instant messaging capability on the device 4 andon the other electronic devices having routines that are subscribers tothe messaging service 62. The messaging service 62 is schematicallydepicted as including a server, although the teachings herein are notlimited to messaging services that employ a server. For instance, themessaging service could, for example, provide a point-to-pointcommunication capability such as is provided with the Bluetoothprotocol, or may provide some other type of communication capability,whether or not wireless.

FIG. 3 further depicts another device 104 as being a device having aroutine that is another subscriber to the messaging service 62.Specifically, the device 104 is an electronic device having a routine160 thereon which can communicate with the messaging service 62 toprovide a messaging capability on the device 104. While the exemplarydevices 4 and 104 are depicted as having a wireless connection with themessaging service 62, it is understood that either or both of thedevices 4 and 104 may employ a non-wireless communication capability andstill not depart from the concept of the invention. It is furtherunderstood that while only the two devices 4 and 104 are depicted inFIG. 3 as being subscribers to the messaging service 62, many moresubscribers to the messaging service 62 may exist but are not expresslydepicted in FIG. 3.

During the course of an electronic conversation, such as depicted inFIG. 4 between, for instance, the devices 4 and 104, a number ofmessages 68 are communicated between the devices 4 and 104. An incomingmessage 72 received on, for instance, the device 4, provides a visualindication of a communication that has been transmitted from, forinstance, the device 104 to the device 4. As can be seen in FIG. 4, anincoming message 72 includes an incoming symbol 66 and an incoming textportion 70. In the exemplary output depicted herein, the incoming symbol66 is a mathematical greater than “>” symbol. The text portion 70 is anexemplary linguistic output that could be of numerous types of forms,such as in different languages, and also can include, for instance,symbols and the like that need not necessarily be a part of anyparticular language.

An outgoing message 76 is depicted as including an outgoing symbol 74,and an outgoing text portion 78. In the exemplary output depictedherein, the outgoing symbol 74 is a mathematical less than “<” symbol.The text portion 78 is an exemplary linguistic output that could be ofnumerous types of forms.

As can be further seen from FIG. 4, the exemplary conversation depictedtherein includes a plurality of incoming messages 72 and a plurality ofoutgoing messages 76 that are transmitted between the devices 4 and 104at a conversational speed, i.e., at a speed in which back-to-backcommunications between the devices 4 and 104 occur without a meaningfuldelay therebetween. Due to the conversational speed of the back-to-backcommunications, the messages 68 do not include an indication of thetimes at which such messages 68 were transmitted, it being assumed as ageneral matter that in such circumstances the specific time at which agiven message within such a conversation occurred may not be ofsignificance to a user.

At a certain point in the exemplary conversation, though, an exemplarymessage 68 which, for example, may be an outgoing message 76, may alsobecome a non-responded-to message 80, meaning that subsequent to itstransmission substantially no additional communication occurs betweenthe device 4 and 104 within a predetermined duration of time. Morespecifically, as the conversation transpires, the back-to-back incomingmessages 72 and outgoing messages 76 are displayed adjacent one another.However, after the expiration of a predetermined duration of time afterthe transmission of a message 68, for instance ten minutes, in whichsubstantially no additional communication occurs between the device 4and 104, the message 68 is determined in accordance with the inventionto be a non-responded-to message 80, and responsive to suchdetermination a first time stamp 84 is output adjacent thenon-responded-to message 80. For instance, if the non-responded-tomessage 80 was transmitted at 2:44 PM, and if substantially noadditional communication between the device 4 and 104 occurs between2:44 PM and 2:54 PM, at 2:54 PM the first time stamp 84 “2:44 pm” isoutput to provide to the users of the devices 4 and 104 an indicationthat the conversation was interrupted at 2:44 PM. Such selectiveoutputting of the first time stamp 84 generally only in response to amessage 68 of some significance, such as the terminal message of aconversation, saves space on the display 50. It is noted that thedisplay of the first time stamp 84 typically will occur on both thedevice 4 and the device 104.

It is understood, however, that the time duration of ten minutes iscompletely exemplary and that the time duration could be set at anyduration. It is also understood that the first time stamp 84 can beoutput in response to the occurrence of additional and/or otherpredetermined events. Moreover, it is noted that the predetermined timeduration may be variable depending upon the characteristics of theconversation. For instance, if messages are being exchanged on a moreinfrequent basis, such as every nine minutes, the predetermined durationof time after which the first time stamp 84 is output may be adjusted tobe twenty minutes, for example.

By way of further example, and as is depicted generally in FIG. 5,another message 68 may subsequently be communicated between the devices4 and 104. Since the message 68 corresponds with a resumption ofcommunication between the devices 4 and 104 after a period ofinterruption, the message 68 is determined to be a resumption message88, and a second time stamp 92 is output adjacent the resumption message88. A user thus can determine from the output on the display 50 theperiod of time during which the conversation was suspended, i.e., thetime between transmission of the non-responded-to message 80 andtransmission of the resumption message 88. Selective outputting of thesecond time stamp 92 saves space on the display 50. In this depictedexample, the first time stamp 84 is disposed, for example, adjacent thenon-responded-to message 80, and the second time stamp 92 is disposed,for example, adjacent the resumption message 88. It is also noted thatthe second time stamp 92 is disposed, for example, between thenon-responded-to message 80 and the resumption message 88.

As the conversation continues after transmission of the resumptionmessage 88, one of the users of the devices 4 and 104 may determine thata time stamp would desirably be displayed in association with a message68, such as if the user wished to emphasize to himself or herself, or tothe other user, the time at which the message 68 was transmitted. Ifsuch a time stamp is desired, the user may activate a user interface 96,such as the exemplary user interface 96 of FIG. 6 a, which can manuallycause the output of an inserted time stamp 98 adjacent the message 68,as in FIG. 6 b. As mentioned above, the inserted time stamp 98 can bemade to appear on both the device 4 and the device 104, and it is alsonoted that, if desired, the inserted time stamp 98 could be made toappear on only one or the other of the devices 4 and 104.

As can be seen in FIG. 7, the output could provide a non-responded-tomessage 180 and a resumption message 188, with a first time stamp 184being disposed adjacent the non-responded-to message 180, and with asecond time stamp 192 being disposed adjacent the resumption message188. However, in the exemplary output of FIG. 7 the first time stamp 184and the second time stamp 192 are disposed adjacent one another and areboth disposed between the non-responded-to message 180 and theresumption message 188. Such an exemplary display of the first andsecond time stamps 184 and 192 illustrates the gap in the conversationthat occurred between transmission of the non-responded-to message 180and transmission of the resumption message 188. It is noted that thefirst time stamp 184 and the second time stamp 192 may have beengenerated in a fashion similar to the generation of the first time stamp84 and the second time stamp 92.

As can be seen in FIGS. 8 a and 8 b, the time stamps can be output inother places. For instance, a text portion of a non-responded-to message280 may have a beginning 282 and an ending 286. Similarly, a textportion of a resumption message 288 may have a beginning 290 and anending 294. In accordance with another aspect of the invention, a firsttime stamp 284 can be output at either the beginning 282 or the ending286 of the text portion of the non-responded-to message 280, and in theexample of FIG. 8 a the exemplary first time stamp 284 is output at thebeginning 282. Also, a second time stamp 292 can be output at either thebeginning 290 or the ending 294 of the text portion of the resumptionmessage 288, and in the example of FIG. 8 a the exemplary second timestamp 292 is output at the beginning 290. Other positioning of the firsttime stamp 284 and the second time stamp 292 are possible within theconcept of the invention.

For instance, and as another example, FIG. 8 b depicts the exemplaryfirst time stamp 284 as being output at the ending 286 while theexemplary second time stamp 292 is output at the beginning 290. FIGS. 8a and 8 b depict different exemplary ways in which the first and secondtime stamps 284 and 292 can be output to provide time data to a user. InFIG. 8 a the first and second time stamps 284 and 292 are disposed at aconsistent location, i.e., at the beginnings 282 and 290 of the textportions of the non-responded-to message 280 and the resumption message288. FIG. 8 b disposes the first and second time stamps 284 and 292generally between the ending 286 of the non-responded-to message 280 andthe beginning 290 of the resumption message 288, which focuses theattention of the user on the interval during which the conversation wasinterrupted. Other ways of outputting the first and second time stamps284 and 292 will be apparent.

Another way of providing time stamps in a fashion that saves space onthe display 50 is depicted in FIG. 9. Specifically, the messages 368 areoutput without displayed time stamps, but upon moving a cursor 374 orother pointing device or other device in proximity to a given message368 a corresponding requested time stamp is output adjacent the message368. In this way, the messages 368 can be provided without alsodisplaying time stamps, but if a time stamp is desired as to any of themessages 368 a requested time stamp 378 can be readily output. In thisregard, the requested time stamp 378 may be output for only apredetermined duration of time, for instance a few seconds, and/or therequested time stamp 378 may be deleted from the display 50 upon adetection of another input, such as from the input apparatus 12 orotherwise. In this regard, all of the messages 368 can have time stampsassociated therewith that are not displayed until requested.

It is also noted that the requested time stamp 378 need not be requestedby the cursor 374, and rather could be requested with virtually anyother type of input desired, such as with a stylus and a touch sensitivescreen, by an actuation of a key, or by the use of alternate pointing orother devices. Other ways of managing the output of the requested timestamp 378 as to any of the messages 368 will be apparent.

It is noted that the appearances of the various time stamps herein iscompletely exemplary, and that the time stamps could be provided in anyformat without departing from the concept of the invention. In thisregard, and in accordance with another aspect of the invention, a giventime stamp may be a smart time stamp and provide additional informationdepending upon the prevailing circumstances. For instance, if the firsttime stamp 84 of FIG. 4 was output as indicated above, and if theconversation was not resumed until the following day, the first timestamp 84 potentially could be configured to automatically change frombeing displayed as “2:44 pm” on the day of communication of thenon-responded-to message 80 to being displayed as, for instance, “2:44pm Thursday” or, for instance, “2:44 PM Sep. 17, 2004” or, for instance,“2:44 pm yesterday” on the following day, although other configurationswill be apparent and will be within the concept of the invention.

Further in this regard, the time stamps can be configured to depictrelative times, i.e., elapsed times, rather than absolute times. Forinstance, and as is depicted generally in FIG. 10, a time stamp 478associated with a message 468 can be output to say, for example, “lessthan one minute ago”, meaning that the message 468 that has beenactivated by the cursor 474 has been transmitted less than one minuteprior to the current time.

Such a time stamp 478 could be configured to be an active time stamp,meaning that it would change as time progressed. For instance, the timestamp 478 could progressively change from saying “less than one minuteago” to saying “one minute ago”, “two minutes ago”, “forty-five minutesago”, and the like as time progressed. Such a time stamp also could beconfigured, for instance, to revert back to displaying an absolute timeafter the expiration of a given time duration. For example, once themessage 468 is one hour old, for instance, the time stamp 478 might beconfigured to no longer output a relative time such as “fifty-nineminutes ago”, and rather to output an absolute time such as “2:54 pm”.Other variations can be provided without departing from the concept ofthe invention.

If it is desired to provide such time stamps that output relative times,it might also be desirable to output such time stamps in any of thefashions set forth above, and such time stamps potentially could beconfigured to be output without first detecting a delay or a break inthe “conversation”. For instance, the time stamp “less than a minuteago” could be displayed immediately upon receiving a message on thehandheld electronic device 4, if such a configuration is desired. Insuch a configuration, and in order to save space on the display 50, thehandheld electronic device 4 may be configured to provide such arelative time stamp only for the most recently transmitted message. Thatis, responsive to detecting the transmission of a message, the handheldelectronic device may be configured to substantially immediately outputa time stamp such as “less than a minute ago”. After one minute the timestamp may be altered to say “one minute ago”, and the like. However,upon the transmission of an additional message, the time stamp for theprior message can be deleted and a new time stamp such as “less than aminute ago” can be provided with respect to the new message.

Such relative time stamps provide to the user an expedited understandingof the timing aspects of the message. That is, the user can understandan aspect of the time of transmission without having to refer to thecurrent time. This advantageously saves effort by the user because iteliminates the mental step of determining the current time andsubtracting therefrom an absolute time displayed by a time stamp todetermine the elapsed time since transmission of the message.

The different fashions of selectively providing intelligent time data inthe form of selectively output time stamps advantageously saves valuablespace on the display 50. Moreover, such selective outputting of timestamps advantageously avoids unnecessary visual clutter on the display50.
